Okay, so this team is completely centralized around the Extreme Killer, Arceus. Every Pokemon on this team is designed to help Arceus survive, open up holes in the opponents team, or set up entry hazards to help Arceus sweep. Also, this is my first post, so if I did anything wrong as far as forum rules go, please let me know. Thanks! Note: I am pretty sure this team is ranked on the Ubers ladder for Pokemon Showdown, but, since the site isn't working at time of posting, I don't know the exact ranking. Arceus @ Silk Scarf Ability Multitype EVs: 252 Atk / 252 HP / 4 SDef Adamant Nature - Extremespeed - Swords Dance - Earthquake - Shadow Claw This is a pretty standard extreme killer set. I run earthquake over brick break because of the extra power. Skarmory and Ferrothorn, two excellent Arceus counters that this set can't answer effectively, are dealt with by other members of my team (Ho-oh and Groudon). Blissey @ Leftovers Ability: Natural Cure EVs: 252 Def / 252 SDef / 4 HP Bold Nature - Heal Bell - Wish - Protect - Toxic Arceus hates burns. He really, really, hates them. Heal bell enables Arceus to fight Giratina and other will-o-wisp users, and, if he gets burned, to be healed easily by Blissey for a second sweep attempt. Also, Wish allows Blissey to restore the HP of Arceus, as well as that of my other Pokemon, many of which are bulky. Finally, Blissey can wall Kyogre barring rain-boosted, max HP water spout. Ho-Oh @ Leftovers Ability: Regenerator EVs: 248 HP / 176 Atk / 88 Spd Adamant Nature - Roost - Substitute - Sacred Fire - Brave Bird Ho-oh is a phenomenal tank, especially under the sun. It takes special hits like a champ and deals out brutal physical damage with it's base 130 Atk stat. Ferrothorn and Skarmory, two of Arceus's best counters, are terrified of Ho-oh. STAB Brave Bird takes a huge chunk out of Kyogre's health, rendering Water Spout impotent and helping me win the weather war. If Arceus dies, sun-boosted STAB Sacred Fire provides an alternate route to victory. Forretress @ Leftovers Ability: Sturdy EVs: 252 HP / 252 Def / 4 SDef Bold Nature - Spikes - Stealth Rock - Toxic - Rapid Spin Entry hazards are a huge help to Arceus when sweeping. Ho-oh hates stealth rock, so rapid spin support is crucial for Ho-oh to be successful. Toxic puts pokemon attempting to set up on Forretress on a tight clock. Pretty standard set, tbh. Groudon @ Leftovers Ability: Drought EVs: 252 HP / 252 Atk / 4 Def Adamant Nature - Stealth Rock - Fire Punch - Earthquake - Swords Dance Groudon boosts the power of fire type moves by 50%, threatening pesky steel types and making Ho-oh an even more serious threat. It takes out Ferrothorn with ease, sets up entry hazards, and is an all around solid lead. Mewtwo @ Leftovers Ability: Pressure EVs: 252 SAtk / 252 Spd / 4 HP Timid Nature - Aura Sphere - Ice Beam - Calm Mind - Psystrike Mewtwo's ability to hit a wide variety of Pokemon either super-effectively or on their weaker defensive stat makes him an extremely versatile offensive threat. He can revenge kill things I normally couldn't answer, and with Calm Mind also functions as an extremely dangerous sweeper. He patches any weaknesses this team might have by killing them. :) Note: I didn't include abilities when that Pokemon had no relevant abilities, or only one ability. Please let me know what you think!
